Mel Needs to park his car for eight hours. Spikes parking place charges five dollars per hour for the first three hours and thre
Dima020 [189]

Answer:

  • Spike's Parking
  • $5 less

Step-by-step explanation:

After 3 hours, Spike charges 6 dollars per hour. For 3 hours, the charge is only $5×3 = $15 (which is $3 less than $6×3). So the rate after 3 hours can be modeled by ...

  s(h) = 6h -3

For 8 hours, s(8) = 6·8 -3 = 45 . . . . dollars

__

After 4 hours, Main Deck charges 8 dollars per hour. For 4 hours, the charge is only $18 (which is $14 less than $8×4). So the rate after 4 hours can be modeled by ...

  m(h) = 8h -14

For 8 hours, m(8) = 8·8 -14 = 50 . . . . dollars

__

For 8 hours, the $45 charge at Spike's is $5 less than the $50 charge at Main Deck.

Mrs. Nestler enjoys listening to classical music. She has the following audio CDs by her favorite composers in her collection: 4
ivolga24 [154]

Answer:

10.55% probability

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the CDs are chosen is not important. So we use the combinations formula to solve this question.

1 Bach CD, from a set of 4.

1 Beethoven CD, from a set of 6.

1 Brahms CD, from a set of 3.

1 Handel CD, from a set of 2.

So, D=144

4 CDs from a set of 4+6+3+2 = 15.

So, T= 1365

p= D/T= 144/1365 = 0.1055

10.55% probability that she will choose one by each composer
